At the end of Thor, the longhaired, hammer-wielding hero and his great love, Jane Foster (a.k.a. Natalie Portman), share an epic, romantic kiss. But, as Portman told the New York Daily News, that wasn't her in the finale make-out.

Apparently, the scene was filmed in reshoots, and Portman's schedule didn't allow her to be there for it—so producers came up with an adorable solution: Gussy up Chris Hemsworth's real-life wife, Elsa Pataky, in Natalie's wig and costume, and let the married couple do what comes naturally. So, unbeknownst to moviegoers, it was Elsa playing Foster in the end.

With all that role-play (HA), it's no surprise that Elsa is expecting their second child (they already have the almost too-precious India Rose.)
